The author of a Rolling Stone article about a rape at the University of Virginia is being pressed in court to explain errors she made while reporting the now-discredited story.

Sabrina Rubin Erdely took the stand Thursday in the defamation trial against the magazine over the 2014 story about the gang rape of a woman identified only as "Jackie." University administrator Nicole Eramo is seeking $7.8 million from the magazine for its portrayal of her.

Eramo's attorneys questioned why Erdely didn't contact the woman's friends who went to her aid the night of the alleged assault or raise concerns about changes in Jackie's account over time.

Erdely said Jackie's changing story didn't bother her because "it takes trauma victims time to come forward with all the details."
